HAVE: Perennial blue Salvia
I have fresh perennial blue Salvia that was a hummingbird magnet this year. I sowed these from seeds I originally got in a Netherlands trade 3 years ago. Botanical name is unknown, but it looks very much like a sylvestris variety but is 4-5 ft. tall. Prolific reseeder too. I'll trade for Black & Blue or something from my Wanted seed list.
